WATER-PURIFIER.

Application filed August 23, 1918.

To all whom it may concern Be it known that 1, JAMES C. ECKLIFF, acitizen of the United States, residing at Detroit, county of lVayne,State of Michigan, have invented a certain new and useful Improvement inWater-Purifiers, and declare the following to be a full, clear, andexact description of the same, such as will enable others skilled in theart to which it pertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification.

This invention relates to water-purifying systems for boilers and hasfor its object the provision of a number of members that 00- operatetogether to purify the water and do away with the necessity of filteringthe feed-water.

In the drawings: Figure 1 is a vertical cross section of a steam boiler.Fig. 2 is a vertical longitudinal section of the same.

Heretofore in order to prevent foreign matter being deposited upon thehot surfaces, such as the crown of the furnace chamber, the crown sheetof the combustion chamber and the fines, filtration of the feedwater hasbeen employed. It is quite necessary, especially on boats on the lakesand rivers, also locomotive and stationary boilers, to prevent thedeposit of mud, sand and other foreign material upon the hot surfaces,for it bakes and becomes scale. This scale is deleterious to theinternal parts of the boiler and must be removed at short intervals. Theremoval is not only an expense but it means that the boiler fires mustbe extinguished for a period while the scale is removed.

The present invention prevents the formation of scale and does away withfiltration of the feed-water, which is not entirely satisfactory. At atemperature of 212 degrees Fahrenheit, a considerable precipitationtakes place, but not complete precipitation. Between 300 degrees to 350degrees Fahrenheit complete precipitation of all extraneous matter inthe water occurs. Most boilers have temperatures ranging from 335degrees to 4.10 degrees Fahrenheit.

It is the object of this invention to utilize such temperatures toprecipitate the extraneous material to a point below the hot surfacesfrom which it may be automatically removed, thereby eliminating the fre-Specification of Letters Patent.

quent cleansing of boilers, and thereby preventing scale. To accomplishthis several old devices are used in a new relation.

Referring to the drawing, the boiler shell is indicated as a, thefurnace as b, the combustion chamber as c, the fiues as (Z, and thestay-bolts as e. A temperature balance f comprises a leg running up overthe side of the furnace and an arm extending along the top of thefurnace lengthwise of same. This is only one form of a temperaturebalance; other temperature balances might be used provided theypositively equalize the temperature at top and bottom.

Temperature balances have already been used for the purpose ofequalizing the heat of the water in boilers. Such equal heating preventsuneven expansion and stresses upon the boiler shell, the furnace shell,the combustion chamber shell and the flues. It is the purpose of thisinvention to heat the feed-water for another purpose, namelyprecipitation.

The feed-water is introduced at the bottom of the boiler so as not to bein a position to drop the particles of extraneous matter suspended in itupon surfaces where they will be baked or from which they cannot beremoved. Ordinarily the introduction of the feed-water at the bottomwould be a dis advantage as it would mix with the already colder stratumat the bottom and make a still greater disparity of temperatures indifferent locations in the boiler. The feedwater pipe is indicated at gand the injector at it. As soon as the feed-water enters the boiler itmeets the hot currents set up by the temperature balance and itselfbecomes heated to a high temperature. This rise in temperature takesplace almost immediately and before the new water has a chance to riseabove the furnace, combustion chamber, or lines. This high temperatureso soon attained immediately precipitates substantially, if not all, theforeign matter in the water before the new water has an opportunity torise above the heated surfaces.

The precipitation takes place directly on the bottom of the waterchamber of the boiler. Here it is not subjected to such intense heat asto become baked, nor is it given time to become caked on the bottom; forthe final step in the invention is to remove the sediment from thebottom of the boiler by the aid of the steam and its pressure. Theblow-01f should be operated at regular intervals to preventaccumulations which might be deposited on highly heated surfaces by thetemperature balance. To accomplish this, a blow-oil 2' is provided,consisting of a main pipe and a plurality of equally spaced legs 7'.These legs'together with the main pipe reach comparatively high upon thesides of the boiler to take in the whole area upon which theprecipitation takes place. The legs are substantially equally spaced soas to aiford an equal chance for discharge from all points on the areaof deposit. The discharge valve is may be opened whenever it is desiredto sweep the bottom of the boiler and the sediment eliminated before ithas time to cake.

It will be noticed that the temperature balance can be used to performits old function of equal heat distribution and can also act in the newcombination to attain a purification of the boiler water without depositon surfaces that cannot be swept while the boiler fires are burning.

I What is claimed 13-5 v a,

1. A water purifier for boilers, having in combination with the steamgenerating boiler, means for substantlally equalizing boiler, atemperature balance for ma-intain-' mg substantially equal temperaturesfor the water in all parts of the boiler, means for introducing the feedwater into the boiler adjacent the bottom of the boiler, and a blow offfor completely sweeping the bottom of the boiler.

In testimony whereof, I sign this specifi cation in the presence of twowitnesses.
